使用Node.js服务器从iOS应用发送文本（电子邮件）

Question

I'm trying to send an mail from my app using a Node.js server. I would want to send the 'from' 'to' and 'content' of the email to the server and he would then send the email to the person.

I have found Nodemailer to use for sending emails, but how can I send the data (from,to,content) from my app to the server? I'm writing my app in Swift.

EDIT:
Here is my code for the app:

func post(params: Dictionary<String,String>, url:String) {
    var request = NSMutableURLRequest(URL: NSURL(string: url)!)
    var session = NSURLSession.sharedSession()
    request.HTTPMethod = "POST"

    var err:NSError?
    var jsonObject = NSJSONSerialization.dataWithJSONObject(params, options: .PrettyPrinted, error: &err)

    request.HTTPBody = jsonObject
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    var task = session.dataTaskWithRequest(request, completionHandler: { (data,response,error)-> Void in

        println(response)

    })
    task.resume()

}

I call this function with parameters like Email, From, To, and Content and send them to the Nodejs server. What would be the correct code for the server to handle the JSON object (send the email) and return 'Success' or 'Fail'? How can I use the JSON object in the server code?

in Node 

/*Config mailer*/
    var nodemailer = require('nodemailer');
    var transporter = nodemailer.createTransport({
      service: 'gmail',
      auth: {
        user: 'xxx@gmail.com',
        pass: 'yyyy'
      }
    });


Create Function 

    function MSGEmail(MSG) {
      // send the message and get a callback with an error or details of the message that was sent
      transporter.sendMail({
        from: 'sender@address',
        to: 'xx@gmail.com',
        cc: 'yy@gmail.com',
        subject: 'Auto Email From server',
        text: MSG
      });
    }



    //Register Event

    client.on('SEND_MSG', function(data, callback) {
      sendEmail(data); //handle msg and pass to funcation
      callback();
    });

    // iOS (ObjC)


    [APPCONTEXT.socketIOHandler.socketIO sendEvent: KEY_SEND_MSG withData: dictionary
      andAcknowledge: ^ (id argsData) {
        if (argsData) {}];

Nodemailer has an API that shows you how to deal with thier module, all you have to do is just proividing these details (from,to,content) to the server side and handle it this way,

var nodemailer = require('nodemailer');
// in case your using gmail as your mail serivce.
var transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        user: 'sender@gmail.com',
        pass: 'password'
    }
});
transporter.sendMail({
    from: 'sender@address',
    to: 'receiver@address',
    subject: 'hello',
    text: 'hello world!'
});
